실험 절차

To a solution of 3-chloro-5-fluorophenol (1.46 g, 10 mmol) and 1-fluoro-4-nitrobenzene (1.41 g, 10 mmol) in acetonitrile (40 mL) was added potassium carbonate (2.76 g, 20 mmol) and the reaction mixture was heated to reflux for 4 hours. After filtration, the solvent was removed. The residue obtained was washed with n-hexane (2 times 15 mL) and dried to afford the title compound (2.38 g) which was directly used in the next step.
